An example of a traffic signal-based advertisement system and its control method for performing bidirectional data communication according to the present invention can be variously applied, and a most preferred embodiment will be described below with reference to the accompanying drawings.

1 is a block diagram illustrating an embodiment of a traffic signal based advertisement system for performing bidirectional data communication according to the present invention.

Referring to FIG. 1, a traffic signal-based advertisement system A for bidirectional data communication includes an advertisement device 100 capable of modularization, a traffic signal controller 200 for controlling an existing traffic signal, And a traffic information center server 300 that controls the traffic signal controller 200 to collect traffic information and collect and manage traffic information.

1, the advertisement apparatus 100 includes a traffic signal controller 200 and a short-range wireless communication network 200 to receive a traffic control signal for controlling a traffic signal (not shown) Data can be transmitted and received through the network. Of course, it is natural that the advertisement apparatus 100 may be connected to the traffic signal controller 200 through a wired communication network.

Accordingly, the advertisement apparatus 100 receives the traffic control signal in conjunction with the traffic signal controller 200, and outputs the advertisement to the entrance side of the road in response to the traffic control signal.

In this case, the advertisement device 100 can be applied to various structures such as a pivoting display structure as shown in Fig. 4 and a fixed display structure as shown in Fig. 7, and through such a structure, ), But it is possible to make active advertisement in various directions.

As a result, the advertisement apparatus 100 controls the advertisement output direction such that the direction in which the advertisement screen is output is directed to the direction of the entrance road on which the advertisement screen is stopped, based on the installed position of the apparatus, .

In addition, the advertisement apparatus 100 may capture the image of the entrance road side and transmit the traffic information of the corresponding area to the traffic information center server 300. [

The traffic signal controller 200 is for controlling a traffic light installed in an area where progress, stop, rotation, attention, or pause is required for the vehicles, such as a crosswalk or an intersection, The traffic signal can be controlled through a traffic control signal including a traffic signal, a type of a traffic signal informing the driver of the traffic signal, a blinking sequence of each traffic light, and a lighting holding time (signal holding time) for each traffic light.

The traffic information center server 300 is a server that operates in a traffic information center for collecting and managing traffic information and controlling traffic flow in a wide area. The traffic information center is a server that performs functions and methods required by the present invention , It is not limited to a specific organization or a company, and can be separated or integrated for each function.

For example, when the traffic information center server 300 simultaneously collects traffic information of each area and controls the traffic flow, the traffic information control server 200 generates traffic control signals for the respective areas and transmits the traffic control signals to the traffic signal controller 200 Lt; / RTI >

At this time, when the traffic information center server 300 establishes a separate communication network from the advertisement apparatus 100, it can simultaneously transmit the traffic control signal to the advertisement apparatus 100 installed in the same area as the traffic signal controller 200 have.

If the traffic information center server 300 does not establish a communication network with the advertisement apparatus 100, the traffic information center server 300 transmits a traffic control signal to the traffic signal controller 200 and the traffic signal controller 200 May transmit the received traffic control signal to the advertisement device 100. [

As another example, in the case where information for traffic control is stored in the traffic signal controller 200 or independently operated as in the case of manual operation in the field, traffic control The signal may be transmitted to the advertisement apparatus 100 and also to the traffic information center server 300 if necessary.

As a result, the traffic control signal is only a means for linking the advertisement device 100 to a traffic light of a corresponding area, and the generation and transmission processes are not limited to specific methods.

1, the advertisement apparatus 100 includes a control signal receiving unit 110, an advertisement DB 120, a display 130, a driver 140, a controller 150, an image capturing unit 160, an image recognizing unit 170 And a traffic information transmission unit 180.

The control signal receiving unit 100 receives the traffic control signal and performs short-range wireless communication with the traffic signal controller 200 as described above or may perform wire / wireless communication with the traffic information center server 300, have.

The advertisement DB 120 stores advertisement images that are exposed (hereinafter, mixed with 'output') on the display 130, so advertisements for various companies or products can be stored. Even if the same products are used, A plurality of different advertisements may be stored. Here, the reason why different exposure times are set for the same product is to actively cope with the case where the maintenance time of the traffic signal in the area is changed due to various reasons. In addition, the advertisement information stored in the advertisement DB 120 may be updated through communication with the outside.

If the advertisement stored in the advertisement DB 120 is a local advertisement, the advertisement may include information on a shop, an enterprise, and products manufactured or sold there in a direction in which the vehicle being stopped is located.

The display 130 displays the advertisement image stored in the advertisement DB 120, and can output the advertisement to the entrance road being stopped by the control unit 150. [

For example, the display 130 may be pivoted in a specific direction by the driver 140, as shown in Figures 1 and 5.

In other words, the advertisement device 100 may further include a driving unit 120 that rotates the display 130. The control unit 150 controls the driving unit 110 to display the display 130 on the entrance side corresponding to the stop signal, .

The control unit 150 checks the traffic control signal received by the control signal receiving unit 110 and calls the advertisement information to be output to the entrance road corresponding to the stop signal from the advertisement DB 120, And then output the corresponding advertisement.

The image capturing unit 160 captures an image of the entrance side of the display 130 in the direction of the display 130. In the case of FIG. 5, one camera may be installed in the same direction as the direction of the display 130, Four cameras may be installed in each direction or two cameras may be installed so as to be rotatable. Of course, in the case of FIG. 8 as well, it is needless to say that one camera can be rotated in all directions according to the traffic signal system to photograph a stopped entryway.

The image recognition unit 170 performs image recognition processing on the image photographed through the camera, which is the image capturing unit 160, to determine whether the vehicle is running or stopped on the current screen. At this time, the image recognition algorithm is not implemented with a complicated algorithm such as license plate recognition, and it is enough to be developed and implemented to improve the processing speed since it is only necessary to determine whether or not the object is moving. Therefore, the development cost and operating cost of the program for image recognition can be minimized.

Accordingly, the control unit 150 may generate the traffic information including the traffic condition image photographed by the image capturing unit 160 by determining the flow of the vehicle by each entrance road.

The traffic information transmission unit 180 may transmit the traffic information generated by the control unit 150 to the traffic information center server 300.

FIG. 2 is a flowchart showing an embodiment of a control method of the advertisement system shown in FIG. 1. FIG.

Referring to FIG. 2, the advertisement apparatus 100 receives a traffic control signal including a traffic signal and a signal retention time of a corresponding area (S100). As described above, the traffic control signal may be transmitted from the traffic signal controller 200 or may be transmitted from the traffic information center server 300, and may include a signal capable of controlling the traffic flow in the current area have.

In particular, the advertisement device 100 confirms the number and type of traffic lights controlled by the traffic signal controller 200 through the received traffic control signal, It is possible to confirm the direction and the number of the access road, and at the same time, the traffic flow to each access road can be confirmed at step S100.

When the characteristic of the area is confirmed as described above, the advertisement device 100 can confirm the display setting information for each access road in the corresponding area according to the traffic control signal (S200). Here, the display setting information refers to information for outputting the advertisement image on the display 130. The display setting information includes an advertisement output time set corresponding to the holding time of the stop signal for the access road, And a signal change waiting time set to be terminated.

For example, in outputting the advertisement image on the display 130, the advertisement device 100 may display the advertisement image on the display 130 in a time period sufficient to secure the forward view even in the process of stopping or running at the time of the change of the signal, Signal change wait time).

In other words, the advertisement device 100 starts to output the advertisement after a predetermined time elapses after the traffic signal is changed to the stop signal, and stops the advertisement before the predetermined time to change from the stop signal to the progress signal, The driver can operate the vehicle smoothly enough at the point of change, thereby improving the concentration of the advertisement and ensuring safe driving.

When the starting time, the holding time, and the ending time for outputting the advertisement are confirmed as described above, the advertisement device 100 confirms the advertisement information to be output to the corresponding entry road according to the display setting information.

Here, the advertisement information may include advertisement classification information classified into at least one of the progress direction, the time period, and the output time.

More specifically, the advertisement information by the progress direction may include an advertisement classified according to the progress direction corresponding to the next traffic signal (straight ahead or left turn) (an advertisement about a shop or a company located in the corresponding lane after passing the corresponding point) The advertisement information for each time period may include advertisements classified according to the current time, and the advertisement information for each output time may be classified according to the current traffic signal retention time (for example, 5 seconds for the same product, 10 seconds for the same product, ) ≪ / RTI >

Accordingly, the advertisement apparatus 100 selects an advertisement for a shop or an enterprise that exists at a position where a driver of the vehicle that is stationary in the entrance road reaches and arrives, or a product that is sold or manufactured there, The user can select an advertisement necessary for the driver and the passengers of the vehicle located in the entrance road, such as selecting the advertisement information for the entrance route. Of course, the selection of such an advertisement can be preset and stored, and it is natural that the advertisement can be changed remotely through the traffic information center server 300.

Thereafter, the advertisement device 100 outputs the corresponding advertisement in the direction of the entrance according to the selected advertisement information (S300).

At this time, as described above, the advertisement device 100 can output an advertisement after a predetermined time elapses after the traffic signal for the access road is changed to the stop signal, and the stop signal for the access road is changed to the next traffic signal You can stop the output of this ad in the past.

Then, the advertisement apparatus 100 can capture the traffic volume by capturing the entrance road through which the advertisement is outputted through the image capturing unit 160, and provide the traffic information including the result to the traffic information center server 300 ( S400).

FIG. 3 is a flowchart illustrating a specific embodiment of step S400 of FIG.

3, the control unit 150 of the advertisement apparatus 100 calculates a stop signal time and a signal change wait time (signal holding time) for a specific access road based on the traffic control signal received by the control signal receiving unit 110, (S411), the advertisement information corresponding to the stop signal time confirmed in the advertisement DB 120 may be called (S412).

Thereafter, when the called advertisement is output through the display 130 (S413), the controller 150 may compare the remaining time of the stop signal with the lapse of the advertisement time and the signal change waiting time (S414).

If the remaining time is longer than the signal change wait time (S415), the current advertisement can be continuously output (S417). If the remaining time is shorter than the signal change wait time (S415) (S416), and can inform the driver to prepare for driving.

On the other hand, since most electric sign boards output specific information using light, the degree of recognition of information may be influenced by the weather. For example, depending on the direction of sunlight, you may not be able to see the information displayed on the board.

2, the traffic information control server 200 transmits a traffic control signal to the traffic information center server 300. The traffic information center server 300 transmits a traffic control signal to the traffic signal controller 200, You can see more information.

In addition, the advertisement device 100 may control the output brightness of the corresponding advertisement in response to the weather information of the corresponding region in the advertisement display step (S400) shown in FIG.

Therefore, the present invention can always ensure a constant visibility irrespective of the surrounding weather, and accordingly, it is possible to transmit sufficient information to the driver of the vehicle being stopped.

4 is a flowchart showing another embodiment of step S400 of FIG.

Referring to FIG. 4, when the image S421 of the entrance road side photographed by the image photographing unit 160 is recognized as an image by the image recognizing unit 170 (S422) as shown in FIG. 1, The image recognition unit 170 may receive the determination result and check the stopped vehicle (S423).

If the checked vehicle is larger than the reference vehicle (for example, two cars for each lane) (S425), the controller 150 determines that the vehicles in the access road have safely stopped according to the stop signal, (S426). ≪ / RTI >

If the identified vehicle is smaller than the reference vehicle (S425), the controller 150 determines that the vehicles in the access road are currently running or stopping, and can wait for output of the advertisement (S427).

As a result, the advertisement device 100 of the present invention can provide a sufficient time for the driver of the vehicle that has not completely stopped after switching to the stop signal by outputting the advertisement after confirming the stop of the vehicle through the camera, By stopping the advertisement before the signal is terminated, it is possible to provide time for preparing an operation for proceeding the stopped vehicle in advance.

Accordingly, it is an object of the present invention to provide a safe environment for the driver to ensure sufficient front view and sufficient operation, to provide a sufficient advertisement effect to the advertiser, It can inform traffic signals continuously and smooth traffic flow.

The advertisement apparatus 100 of the present invention can transmit traffic information including the image photographed by the image photographing unit 160 shown in FIG. 8 to the traffic information center server 300 through the traffic information transmitter 180 .

In addition, the advertisement device 100 of the present invention recognizes the weather of the corresponding region by performing image recognition processing on the image photographed by the image photographing unit 160, and controls the output luminance of the display 130 to display advertisement and traffic signal information Can be output.

5 is a diagram showing an embodiment of the advertisement apparatus shown in FIG.

Referring to FIG. 5, the advertisement device 100 may be formed in a rectangular shape having a display 130 on one side thereof, and a driving unit 140 may be provided on the lower side to rotate the display 130.

In particular, as shown in FIG. 5, the display 130 may be divided into an advertisement display 131 for outputting an advertisement and a traffic signal display 132 for outputting information on a traffic signal.

In this way, when the information on the traffic signal is output to the traffic signal display 132 together with the advertisement display 131, the driver of the vehicle in the stop state prepares in advance what direction the traffic signal will travel in the next few seconds So that not only the information about the advertisement but also the traffic flow can be smoothly provided and the driver can sufficiently assist in safe driving.

In FIG. 5, the reference character 'P' denotes a support for installing the advertisement device 100, and the substructure of the support can be modified in various ways according to the needs of a person skilled in the art.

FIG. 6 is a conceptual diagram illustrating a method of operating an active advertisement system at an intersection using the advertisement apparatus of FIG. 5;

6 shows an example in which the system of the present invention is applied to an intersection intersection. The advertisement device 100 is installed at each corner portion, and each advertisement device 100 (left side and right side in Fig. 6) ) So that the passenger of the stopped vehicle can easily see the advertisement.

In other words, the advertisement information can be transmitted more efficiently by controlling the direction of rotation differently according to the position where each advertisement device 100 is installed.

Also, according to the needs of those skilled in the art, only two or one of the four advertisement devices 100 shown in FIG. 6 may be operated.

For example, in the case where there are many lanes in each access road (for example, four lanes in a round trip, etc.), the advertisement apparatus 100 can be installed at each corner portion. In the case where there are few lanes It is possible to install two advertisement devices 100 in a diagonal direction, and in a single lane equipped with a crosswalk, one advertisement device 100 can be installed to operate the system.

Accordingly, the present invention can be installed and operated independently of structures for installing facilities such as existing traffic lights, and is not limited by the size and the form. Therefore, as described above, Advertising can be possible.
